The operator then immediately releases the key 51', which is returned to normal position by a spring 69. The lever 61 has a returning spring; 82 The typewriter has the usual set of type operating keys, includin alphabet keys and also including numeral Leys 88 mounted on levers 88 and connected by hell cranks 81? to type bars 90, which are thrown back against a platen 91 mounted on a carriage 92. The carriage is power-driven, and has a rack 87 meshing with a pinion 86, con nceted with an escapement wheel 85. the. latter controlled by dogs 8-1, operated by a universal bar 83, which is actuated hy the type. liars, so that whenever any type hey is tuated, the carriage 92 is caused to feed a letter space.

Fastened at the hack of the carriage. 92, are brackets 93. carrying a rack 9i. to receive adj listahie cams or tappets 95. di heriever any tappet, during the travel of the ca rriage, passe beneath the set of jacks an, it raises the forward ends of the jacks in succession. turning each on its pivot :17. anti depressing its rear end to press down the corresponding one of a set of wires 98. These wires are eoi'inected at their lower ends to levers 9 on a fulcrum rod 100..

Each lever 99 raises one of a. set of link ages 101, each linkage havinga pin 102 to lift the rear end of a rack 103, the forward end of which meshes with a pinion 10 t connected to a computing wheel or dial. 195? Each rack carries a set of pins 106. and one of these is depressed by the operated type key 88; each key having a stem 110. for this purpose. to depress a crank 112. fast to a shaft 113, which is connected to a linlta c 114, to depress one of the pins 1116 upon the lifted rack bar 103; there being one linkage 1H for each key, each linkage being in poshion to depress a corres jmnding pin 106 on which ever rack oar is lifted. as set forth in said application. After the keys 88 are ma nipulated to write a nnm er, and the corresponding racks 103 accordingly elevated as the paper *arriage feeds along), and certain pins 104.3 thereon depressed, thu temporarily registering a number on said pins, there i caus d a reciprocation of the rack frame 125 to carry the registered rnunhers into the dial wheels 1033. This frame 13 usually includes :r pair of arms 115) connected a transverse horimntal bar 111). which in position to engage all the displaced pins 1G5, and to give corresponding forward endwise movements to their racks 1133, thereby turning the dial wheels 105 accordingly, the ret n movements of the racks not turning said wheels, however. because of a pawlanw ratchet connection (not shown) between said wheels and their drive pinion-s i l -l. Pinions 111i meshing with racks 13. are. also in mesh with segments no" tin-ed on rock shaft 111%, and when the slide 15 is disconnected from the yoke 14 said general operator may be operated manually by a handle on said rock shaft 116.

The tahulating mechanism usually employed on the Underwood typewriter, comprises a series of independently operable keys 120. arranged at the front of the typewriting machine on the forward ends of levers 21, the latter pivoted at 122 and connected at their rear ends to upstanding decimal stop rods 123, any of which. may he lifted by its key to engage a column stop 12 1 on said paper carriage. Each column stop rod has a lug 125, and any of these lugs may operate a lever 126, connected by link 127 to a releasing lever 128, the latter adapted to lift the carriage rack 87 from the pinion S15.

Beneath the forward ends of the tabulating key levers 121, extends a horizontal transverse universal bar 129, depressihle by any of the tahulating keys 120, said bar 129 mounted on the forward ends of a pair of arms 130, 131, rigidly connected by a rock shaft 132 extending across the machine, and journaled in the framework. A spring 133 holds up the universal bar.

Upon depression of any of the tabulating keys 12%, said universal bar 129 is depressed, and. a finger 134 on one end thereof bears down upon an arm 135, mounted upon said stein so as to carry down said stem and release the latch 40, thereby closing the cireui through the motor, and clutching the motor to the general operator 13. The operator releases the key 120, preferably after the carriage has completed its run, or before the completion of the cycle of movements of the operator 13, so that the latch 40 is returned to normal position, and intercepts the car 43 and the dog 41. Hence when any t'ahulating key is depressed, it effects not only the tahnlating operation, but also an operation of the general operator 13.

1V hen it is desired to silence the tabulating keys in re pect to the latch 40, so that said keys may he operated without all'ecting the motor or the clutch, the arm 13.5 may lie swung doun from the position at Fig. 7, so that it cannot be reached by the finger 13% upon the universal bar 129.

A detent 136 is fixed to the arm 135, which is pivoted at 137 to the stem 58; said detent having a pin 138 which may be sprung into either of: two holes 139 on said stem.

By having a plurality of tappets or earns '95. described above, it. is possible to do cross'adding with a single totalizer. All that is necessary is to have one of said tappets 95 for every column in which it is desired to compute in the totalizer, and the denominational tahnlating keys 120 may suc cessivcly position the carriage in these varions columns. In ordinary machines it is pui'zitinn. Tim present invention does: away 8]"1UI'P1} with the couiumnn reuniting from fm'gutting to prvsri maid key, for ihe tubu iz-iiingr keys (ii) iis wnrii,
